Two configurational approaches on the modelling of continuum dislocation inelasticity

The main focus of this contribution consists in the elaboration of a continuum modelling approach accounting for dislocation-based quantities. Related deformation dependent history-variables are attached to individual material points and, moreover, are extended by means of gradients thereof so that so-called weak non-localities are captured. These gradients of internal variables may be further spe

A production performance analysis regarding downtime and downtime pattern

In order to compete on the international market, companies today need to optimize their production continually. One way to achieve this is to minimize the frequency and length of downtime in the production. The downtimes in a particular manufacturing line were classified on the basis of what generated them; a production performance analysis was carried out, and then a cost model was applied to the
